Domestication through clandestine cultivation constrained genetic diversity in magic mushrooms relative to naturalized populations

Current Biology December 1, 2023 Alistair R. Mctaggart, Stephen Mclaughlin, Jason C. Slot et al. 6 citations

Fungi that are edible or fermentative were domesticated through selective cultivation of their desired traits. Domestication is often associated with inbreeding or selfing, which may fix traits other than those under selection, and causes an overall decrease in heterozygosity. A hallucinogenic mushroom, Psilocybe cubensis, was domesticated from its niche in livestock dung for production of...

A whole genome atlas of 81 Psilocybe genomes as a resource for psilocybin production.

F1000Research September 23, 2021 Kevin Mckernan, Liam T. Kane, Yvonne Helbert et al. 10 citations

The Psilocybe genus is well known for the synthesis of valuable psychoactive compounds such as Psilocybin, Psilocin, Baeocystin and Aeruginascin. The ubiquity of Psilocybin synthesis in Psilocybe has been attributed to a horizontal gene transfer mechanism of a ~20Kb gene cassette. A recently published highly contiguous reference genome derived from long read single molecule sequencing has...

A draft reference assembly of the Psilocybe cubensis genome

F1000Research June 15, 2021 Kevin Mckernan, Liam T. Kane, Seth Crawford et al. 10 citations

We describe the use of high-fidelity single molecule sequencing to assemble the genome of the psychoactive Psilocybe cubensis mushroom. The genome is 46.6Mb, 46% GC, and in 32 contigs with an N50 of 3.3Mb. The BUSCO completeness scores are 97.6% with 1.2% duplicates. The Psilocybin synthesis cluster exists in a single 3.2Mb contig. The dataset is available from NCBI BioProject with accessions...
